New Duex2,3,4,5?

If you just want the third filament to stay put, can you not just arrange a way to fix the filament in place until you get the duexn?

I thought of that but the problem with the Diamond hot end is that normal retraction doesn't work- - all that happens is that it draws filament from an unused input rather than from the nozzle. Therefore, I have to use firmware retraction to retract all 3 filaments simultaneously. So just wedging some filament in place will effectively give me no retraction. The other thing that happens is that, if you don't extrude any filament from one of the inputs for a long time, they become blocked at the heat sink. I suspect it's heat creep, due to heating the filament but not extruding any. Or maybe it's pressure on the "in use" input pushing melted filament back up the "unused" input.

The other possibility would be to make a small converter board or even just a cable to convert the Duet WiFi expansion connector pinout to the DueX4 pinout.
Er, yes but I don't have a DueX4.

No worries, I will get the level shifter ordered and put one together. It wont be mega expensive.

Any eta on when a Duet Wifi expansion board will be ready for order? I have my Duet Wifi but have not installed it yet as I need to have at least 3 extruders. I would rather not deal with a temporary solution as I kind of have my Azteeg X3 Pro working alright but Marlin is frustrating me. The Atmel processor just isn't fast enough to do everything it should.
I think I will be taking the machine offline to switch from long bowden systems to Flex3Drives fairly soon. While I do that would be a good opportunity for me to swap the Duet Wifi and expansion boards in.
Also, really glad that the Wifi and expansion board have endstops for extruders. Filament present sensor has been one of my planned features for my machine!

We are working on it right now but I can't give a definite ETA yet. I should have the prototypes ordered next week at which point I will have more clarity and will post an update.

Awesome to hear. Thanks for the insight!

One of the features we are considering for the DueX2/DueX5 is an on-board switching regulator to provide a 12V supply when Vin is higher (typically 24V). This would facilitate using 12V fans and 12V LED strips. It would add about £5 to the retail price of the board. Those of you who are interested in expansion boards, do you think this is a good idea, or not worth the extra cost?

My twopence worth - excellent idea. Cheaper than a 24v DC to 12V DC converter and the wiring will be much more elegant. It gives users the flexibility to source fans/led lights in both 12 or 24v versions so much more choice. I'd be happy to pay the fiver.

I also agree.

This would be super delightful.

Make it so!

This feature has been included in the prototypes that are being manufactured.

Just a small cheap board with 10 pin dual row IDC plugs for each axis. In the future I would like to see a Duet Wifi version that is setup for all the axis outputs go to IDC plugs for external drives for bigger machines and integrated stepper motors where the drive is on the motor.

The 12V conversion to allow for LED and fans when running a 24V printer is awesome. I wish I saw this thread sooner because I would have suggested maybe a CAT5 internet jack to be able to plug in the Duet or use the Wifi feature. Bit of best of both worlds. Not sure if that would even be possible, but would have been a "nice to have". I also love the idea of the Duex2. I don't know if I would have used all 5 extras, but with multi extrusion becoming more popular I think the need for extra 5 can be more of a reality. Since the PCB will be the same on the Duex2, how hard would it be to add more divers to the board (for a common man) if at all possible.

jmjcoke - a simple breakout board is a request I am tracking - just not sure how popular it would be.
danzca6 - Ethernet would not really be feasible on the expansion board without a radical redesign of how the hardware works that would end up with a sub optimal solution. Regarding adding the other components to the Duex2 you would need to be comfortable with working with surface mount components and have a appropriate re-work station, its certainly not impossible but would not be something I would suggest as a first project for somebody just getting into that sort of electronics work. You would, however, be able to connect an external driver relatively simply.

One of our printers is quite large and we decided to use M542 drivers for 3Nm nema24 Z axis motors.
The printer works on RUMBA (Atmega 2560) electronics by RepRapDiscount and we just connected M542 instead of stepsticks.
They work very well.
Another thing is we tried to use servos with DCS 303 drivers from leadshine. It was a great learning opportunity although we dropped it for a while because of some positioning inaccuracies probably due to signal duration differences.So rounding things up…DUEX is a very special thing used to build extraordinary machines and force them to tackle impossible tasks.
It could have some potential for some of us to have the STEP and DIR pins broken out which not neccessary is a hard thing to do depending on development stage. Probably it's late to bring it up or it already had been but I found the forum a few days ago just to be staggered with how dunamic it is and put this idea.External drivers possibility all the way.
